Draw a model of the convection currents in Earth's mantle.
Describe a convection current and its role in moving Earth's lithospheric plates.
Explain the Rock cycle and the different characteristics of Igneous, Sedimentary, and Metamorphic Rocks.
Make observations of rock samples.
Classify rock samples based on observations.
Define minerals.
Explain each of the physical properties that can be used to identify a mineral; color, luster, hardness, streak, density, crystal shape, cleavage and fracture.
Identify unknown minerals using physical properties.
Define igneous rock, extrusive & intrusive igneous rock, and crystallization.
Analyze the size of crystals that form from a solution under different cooling conditions.
Analyze the properties of a volcanic ash sample and its general composition.
Develop a working definition for the word "ash."
Observe samples of rock formed by consolidated ash.
Investigate how volcanic ash erupts into and settles out of the air.
Determine how the size of airborne materials affects where and how fast they settle.
Draw conclusions about how weather conditions affect the direction and speed at which ash moves.
Identify constructive and destructive effects of ash fall (land formation, human health, weather).
Analyze causes and effects of volcanic eruptions and the ability of scientists to forecast volcanic activity.
Classify the effects of volcanic eruptions as destructive or constructive.
Explain the characteristics that differentiate between Composite, Shield, and Cinder Cone volcanoes.
Identify and compare the viscosity of liquids.
Observe changes in viscosity when liquids are mixed with a solid or heated.
Define viscosity and relate the viscosity of lava to the type of volcano it forms.
Model the movement of molten rock through fractures in the lithosphere, over Earth's surface, and under water.
Devise working definitions for the words magma and lava.
Identify landforms created by molten rock.
Define hotspot.
